Description

Technical Field

[0001] This application relates to the technical field of seed control culture, and in particular to a seed growth characteristic control culture device. Background Technology

[0002] Currently, in the fields of agricultural scientific research and germplasm resource development, accurately obtaining data on the growth characteristics of different seeds under differentiated environments plays a crucial role in variety improvement. Traditional field experiments are limited by the uncontrollability of natural conditions, while laboratory cultivation devices need to simultaneously achieve core functions such as independent control of multiple sets of environmental parameters and dynamic data comparison and collection.

[0003] In the existing technology, the current mainstream technical solutions mainly adopt two types of implementation methods: one is a cluster-type incubator group based on multiple chambers in parallel, which constructs different environmental groups by setting up multiple independent incubators; the other is an integrated incubator with a layered turntable structure, which switches the sample to different temperature and humidity areas by rotating the tray.

[0004] However, the cultivation device requires high-precision environmental simulation capabilities and standardized control experimental conditions. In the above-mentioned existing technology, due to the multiple independent incubators, adjacent incubators cannot guarantee that the seeds are in the same growth state before conducting different environmental simulations, which affects the accuracy of the seed control cultivation results. Summary of the Invention

[0005] To improve the accuracy of seed control culture results, this application provides a seed growth characteristic control culture device.

[0006] This application provides a seed growth characteristic control cultivation device, which adopts the following technical solution:

[0007] A seed growth characteristic control culture device, comprising:

[0008] The enclosure has an internal mounting slot and a movable door on one side.

[0009] The platform has two sections, both of which can be detachably embedded into the mounting slot via a slide rail mechanism;

[0010] A first culture medium is provided corresponding to the stage and is provided on the stage, and has a first culture chamber for cultivating seeds.

[0011] Two lifting platforms are provided, each corresponding to the loading platform, and slide on the loading platform via a lifting mechanism;

[0012] The second culture medium is provided corresponding to the lifting platform and is located on the lifting platform, adjacent to the first culture medium, and has a second culture chamber that communicates with the first culture chamber.

[0013] The lighting mechanism includes a light source and a side lighting plate. The light source is rotatably mounted above the platform, and the side lighting plate is mounted on the side wall of the housing.

[0014] By adopting the above technical solution, the box body is provided with a matrix of mounting slots. The double stage is embedded in the mounting slot through the slide rail mechanism. The double lifting stage slides on the stage through the lifting mechanism. The culture medium is divided into a first culture chamber (stage) and a second culture chamber (lifting stage). The lighting mechanism includes a rotating light lamp and a side supplementary light plate.

[0015] Seeds are sown in the first and second culture chambers and pushed into the box via a sliding rail mechanism. Then, the light lamp is rotated to adjust the light incident angle, the side light plate is used to supplement the side light intensity, and water is applied. The growth of the seeds is then observed. By adjusting the height of the lifting platform, the seedlings can be placed in the same layer, but their height from the light source and water source can be changed, thus simulating production under different moisture, light and temperature conditions.

[0016] Experiments with different treatment groups (such as normal group and stress group) were conducted simultaneously to eliminate batch differences; the height of the second culture chamber was adjusted by lifting the platform to control the substrate moisture content (e.g., reducing water supply after lifting to simulate drought); the lifting platform moved the plants closer to / away from the light source to precisely adjust the light intensity; by simulating different environments after the seeds were in the same growth state, the accuracy of seed control culture was improved and variable errors were reduced.

[0017] Optionally, a partition can be detachably connected between the first culture medium and the second culture medium.

[0018] By adopting the above technical solution, the first and second culture media can be cultured in layers using a partition. Initially, the partition is inserted to allow the two culture media to operate independently (e.g., the left side is normally watered, while the right side is treated with drought). The partition is removed midway through the experiment to observe the root growth response across zones. The physical partition blocks the lateral diffusion of water and salt (salt concentration cross-contamination rate <1%). The independent / connected mode can be switched to study root hydrotropism or salt aversion.

[0019] Optionally, a clearance groove is provided on the top wall of the housing, and a top cover is slidably connected to the clearance groove, the top cover sealing the clearance groove.

[0020] By adopting the above technical solution, when the lifting platform rises, the top cover automatically opens the clearance groove along the slide rail; during the experiment, the top cover is closed to maintain the CO2 concentration in the chamber (e.g., set to 800ppm).

[0021] Reduces environmental interference (condensation caused by temperature and humidity differences between the inside and outside of the box is reduced by 90%); the sliding top cover saves operating space compared to traditional hinged covers.

[0022] Optionally, the clearance groove corresponds to the lifting platform, and the lifting platform can slide into the clearance groove and is sealed to the clearance groove.

[0023] By adopting the above technical solution, during cultivation, seedlings in the middle stage of growth can be planted on the upper platform. After the seeds in the lower layer germinate and form seedlings, the second cultivation chamber can be raised to the upper space by activating the lifting platform, so that different environments can be simulated for the same growth stage. By changing the growth environment, different environments can be simulated, and the adjustment of the external environment (such as light, temperature, humidity, and carbon dioxide concentration) between the upper and lower layers can be reduced, thereby reducing energy waste.

[0024] Optionally, a placement groove is provided on one side of the stage, and multiple matrix layers are provided in the placement groove. The multiple matrix layers are arranged vertically in a vertical direction, and the multiple matrix layers form a salt concentration gradient in a vertical direction.

[0025] A physical isolation layer is provided between two adjacent matrix layers. The physical isolation layer is permeable to water and restricts the migration of salt ions. Both the first culture chamber and the second culture chamber are connected to either of the matrix layers.

[0026] By adopting the above technical solution, a multi-layered vertical salt gradient matrix layer is set on the side of the platform, with a water-permeable salt-barrier isolation layer between the layers; the placement tank is filled with a layered salt concentration gradient matrix (bottom layer 1.0%, middle layer 0.5%, top layer 0.1% NaCl), with ceramic filter sheets (pore size 0.5μm) sandwiched between the layers; when the lifting platform rises, the water in contact with the roots comes into contact with the upper high-salt matrix, changing the salt growth environment; through vertical salt gradient simulation, it more closely resembles the salt accumulation phenomenon in natural saline-alkali land; root response tracking accurately records the time and morphological changes of roots penetrating different salt layers (such as a 40% decrease in root hair density); salt stability: the high salt barrier rate of the physical isolation layer can reduce salt fluctuations.

[0027] Optionally, both the platform and the lifting platform are provided with heat insulation cavities, which are filled with heat insulation material.

[0028] By adopting the above technical solution, in the high-temperature experiment (40℃), the heat insulation cavity blocks the heat conduction between adjacent rooms; the day and night temperature difference is simulated with the help of the light lamp (35℃ during the day / 25℃ at night); thermal interference is suppressed: the thermal conductivity is reduced from 2.5W / m·K to 0.8W / m·K; and the temperature deviation in the high-temperature stress experiment is reduced.

[0029] Optionally, the lifting mechanism includes a lifting frame and a lifting assembly. The lifting frame slides on the housing and forms a support platform for supporting the lifting platform. The support platform can be flush with the slide rail mechanism in its initial state.

[0030] By adopting the above technical solution, the lifting frame is controlled to rise or fall by the lifting component without affecting the installation of the lifting platform and the loading platform. In the initial state, the support platform is flush with the loading platform, which is convenient for loading samples. The support platform is raised by driving the lifting frame to raise it by 2mm per day to simulate soil erosion. The programmed lifting supports long-term unattended experiments.

[0031] Optionally, the platform can slide vertically relative to the mounting groove, and an electromagnet is provided on the contact surface between the platform and the lifting platform, while a magnetic block is provided on the contact surface between the lifting platform and the platform.

[0032] By adopting the above technical solution, electromagnets and magnetic blocks are provided on the contact surfaces of the platform and the lifting platform. When energized, the electromagnets attract the magnetic blocks, fixing the movement between the platform and the lifting platform. When energized, the electromagnets (with a magnetic force of 50N) attract the magnetic blocks, fixing the position of the lifting platform and driving the platform to rise synchronously. After the attraction is released, the lifting mechanism can drive the lifting frame and the lifting platform to rise independently. Through the above operations, the simulation environment is enriched, and the universality and accuracy of the equipment are improved.

[0033] Optionally, a partition plate may be detachably provided at the connection between the placement tank and the first culture chamber or the second culture chamber.

[0034] By adopting the above technical solution, the salt flow between the first or second culture chamber can be eliminated through the setting of the partition plate. When the partition plate is inserted, it prevents the roots from entering a specific salt layer (such as isolating a 1.0% NaCl layer). The partition plate is removed in the later stage of the experiment, allowing the roots to expand freely. Staged stress: the salt exposure sequence can be controlled as needed (such as first adapting to 0.1%, then contacting 0.5%). Selective observation: the specific effects of a certain salt layer on the roots can be studied separately.

[0035] Optionally, the placement tank is connected to a water supply mechanism, which is used to regulate the water level in the placement tank.

[0036] By adopting the above technical solution, the water supply is regulated by a flow meter (accuracy ±0.1mL / min) to simulate drought (5% water content) or flooding (saturated water content); the water level sensor provides real-time feedback and automatically compensates for evaporation loss; dynamic humidity control is performed to reduce the fluctuation of substrate moisture content; it can perform accurate simulation and support gradient drought experiments.

[0037] In summary, this application includes at least one of the following beneficial technical effects:

[0038] 1. Simultaneously conduct experiments with different treatment groups (such as normal group and stress group) to eliminate batch differences; adjust the height of the second culture chamber by lifting the platform to control the substrate moisture content (e.g., reduce water supply after lifting to simulate drought); move the plants closer to / away from the light source by lifting the platform to precisely adjust the light intensity; improve the accuracy of seed control culture and reduce variable errors by simulating different environments after the seeds are in the same growth state.

[0039] 2. Through vertical salt gradient simulation, it more closely resembles the surface salt accumulation phenomenon in natural saline-alkali land; root response tracking accurately records the time and morphological changes of roots penetrating different salt layers (such as a 40% decrease in root hair density); salt stability: the high salt resistance of the physical isolation layer can reduce salt fluctuations.

[0040] 3. It enables dynamic humidity control to reduce substrate moisture content fluctuations; it can perform accurate simulations and support gradient drought experiments. Attached Figure Description

Detailed Implementation

[0045] The following combination Figures 1 to 3 This application will be described in further detail.

[0046] This embodiment discloses a growth characteristic control culture device.

[0047] The seed growth characteristic control cultivation device of the present invention achieves simultaneous simulation and control experiments of multi-factor growth conditions through modular mechanical structure and precise environmental control technology. The device is centered on a housing 100, which integrates a detachable stage 210 and a height-adjustable lifting platform 230. Combined with a layered culture medium and an adjustable lighting mechanism 500, it supports independent or combined control of various environmental parameters such as salinity gradient, water stress, and light distance. The structure, connection relationships, and working process of each component are described in detail below with reference to the accompanying drawings.

[0048] like Figure 1 As shown, the box 100 is welded from high-strength aluminum alloy profiles. An installation groove 110 is provided in the interior along the vertical direction, and an opening is provided on one side. A box door is rotatably connected to the opening. A sealing strip is provided on the box door and is embedded in the door seam to seal the internal space of the box 100 and ensure airtightness when closed.

[0049] Reference Figure 2 and Figure 3 The inner wall of the mounting groove 110 is provided with a slide rail mechanism 300, on which a platform 210, a placement groove 600 and a lifting platform 230 are provided. The slide rail mechanism 300 is used for pushing and locking the platform 210, the placement groove 600 and the lifting platform 230. A clearance groove 120 is provided on the top of the box 100 to match the movement path of the lifting platform 230.

[0050] The mounting slot 600, the platform 210, and the lifting platform 230 are all made of 304 stainless steel plate and can be detachably embedded into the mounting slot 110 via the slide rail mechanism 300. The slide rail mechanism 300 includes a stainless steel guide rail 310, a slider 320, and a limit stop. The surface of the stainless steel guide rail 310 is coated with a 0.1mm thick polytetrafluoroethylene coating, with a friction coefficient ≤0.05. Two sets of stainless steel guide rails 310 are provided, arranged vertically on the inner wall of the mounting slot 110. Each set of stainless steel guide rails 310 includes two, arranged in parallel, and located on both sides of the opening of the box. The slider 320 is slidably connected to the stainless steel guide rail 310. There are two mounting slots 600, each corresponding to one of the sliders 320 on both sides, and the mounting slots 600 and sliders 320 are fixedly connected. The platform 210 and the lifting platform 230 are located between the two mounting slots 600. Support plates 280 are provided on the adjacent side walls of the mounting slots 600. The support plates 280 support the platform 210 and the lifting platform 230. The support plates 280 are provided with locking blocks 290, which are vertically arranged and located on the side close to the platform 210. The platform 210 and the lifting platform 230 are both equipped with locking plates, and the locking plates have locking grooves 211, which engage with the locking blocks 290. A limiting block is provided in the mounting slot 110, which can abut against one end of the mounting slot 600, and emits an audible "click" sound when it abuts to indicate that the installation is in place. When the platform 210 is pushed into the mounting slot 110 along the slide rail, the limiting block locks the platform 210 and the box 100 are connected.

[0051] The first culture medium 220 is fixed to the upper surface of the stage 210, and a first culture chamber 221 is formed inside it. A culture base is placed inside the first culture chamber 221 for placing seeds. A first connecting groove 222 is formed on the side wall of the first culture chamber 221 near the placement tank 600, and the first connecting groove 222 is located on the side near the bottom wall of the first culture chamber 221. Three matrix layers are vertically stacked inside the placement tank 600: top layer: 1.0% NaCl-vermiculite mixed matrix, 60mm thick; middle layer: 0.5% NaCl matrix, 60mm thick; bottom layer: 0.1% NaCl matrix. The NaCl matrix is ​​80 mm thick. A physical isolation layer 260 is set between the layers. The physical isolation layer 260 includes a microporous ceramic filter 261 (pore size 0.5 μm, porosity 75%), a unidirectional filter membrane, and a honeycomb partition 262. The microporous ceramic filter 261 is set between adjacent matrix layers and the edges are fixed by silicone sealing rings. The unidirectional filter membrane is set on one side of the placement tank 600. A water outlet 610 is opened on the side of the placement tank 600 where the unidirectional filter membrane is installed. After the water outlet 610 is covered by the unidirectional filter membrane, a honeycomb partition 262 is also installed. The honeycomb partition 262 is used to reduce the damage of the root system to one side of the placement tank 600. The first connecting groove 222 can gradually connect with the three matrix layers.

[0052] The second culture medium 240 is located on the lifting platform 230 and has a second culture chamber 241. Its structure is the same as that of the first culture medium 220. The two are connected and communicated through a communication port. A partition 250 is slidably connected to the side wall of the first culture medium 220 and the second culture medium 240, which are close to each other and have a communication port. The partition 250 is used to separate the first culture chamber 221 and the second culture chamber 241. A partition plate 270 is slidably connected to the side of the placement tank 600 with a water outlet 610. The partition plate 270 is used to separate the communication between the first culture chamber 221 or the second culture chamber 241 and the placement tank 600. After the partition plate 270 is removed, the corresponding salt layer can enter the first culture chamber or the second culture chamber through the one-way filter membrane and the honeycomb partition 262 by dissolving in water.

[0053] The lifting platform 230 is sealed to the side wall of the carrying platform 210, meaning that sealing rings are provided around the periphery of both the carrying platform 210 and the lifting platform 230. The sealing rings on the carrying platform 210 abut against the mounting groove 600 and the lifting platform 230, and the sealing rings on the lifting platform 230 abut against the mounting groove 600 and the carrying platform 210. A lifting mechanism 400 is provided on the housing 100, and the lifting platform 230 achieves vertical movement through the lifting mechanism 400. The lifting mechanism 400 includes a lifting frame 410 and a support platform 4... The lifting assembly 420 and the lifting frame 410 are vertical rods that slide vertically on the side wall of the mounting groove 110. A sliding groove is provided on the inner wall of the housing. The vertical rod slides in the sliding groove and is fixedly connected to the support platform 430. The support platform 430 slides in the mounting groove 110 and can be flush with the upper end surface of the stainless steel guide rail 310. The support platform 430 abuts against the side wall of the lifting platform 230 near the bottom. The lifting assembly 420 is connected to the vertical rod and is used to drive the lifting rod to slide.

[0054] The lifting assembly 420 can be a linear motion structure such as a motor gear rack, a cylinder, an electric push cylinder, or a linear module. In this embodiment, it is preferably an electric push rod and a control module. The cylinder body of the electric push cylinder is fixedly connected to the outer wall of the housing, and the piston rod of the electric push cylinder is fixedly connected to the vertical rod. The control module is set on the housing 100, with a built-in PID algorithm to support programmed lifting (such as raising by 2mm per day to simulate soil erosion, or raising it once to the lower lifting platform 230 being flush with the upper loading platform 210).

[0055] A clearance groove 120 is provided on the upper top wall of the housing 100. The position of the clearance groove 120 corresponds to the position of the lifting platform 230. The lifting platform 230 can slide into the clearance groove 120. A top cover 700 is slidably connected to the housing 100. A top rod slides in the clearance groove 120 and is provided with a sealing strip around its perimeter. The sealing strip abuts against the clearance groove 120 to form a seal. A top rod is provided on the upper lifting platform 230. The top rod abuts against the top cover 700 and pushes the top cover 700 out of the clearance groove 120. The length of the top rod is less than the movement distance of the upper lifting platform 230. When the lifting platform 230 rises to the clearance groove 120, the sealing strip is compressed to form an airtight interface, isolating the upper and lower environments.

[0056] A magnetic block is fixedly installed on one side of the side wall of the lifting platform 230, the placement slot 600, and the loading platform 210 that are close to each other. The magnetic block is set in the vertical direction, and an electromagnet is fixedly installed on the opposite side. The electromagnet and the magnetic block are attracted to each other and can be attracted in a vertically misaligned manner.

[0057] A lighting mechanism 500 is installed inside the box 100. The lighting mechanism 500 includes an adjusting arm 530, a light lamp 510, and a side supplementary lighting plate 520. The light lamp 510 is installed on the top of the box via the adjusting arm 530. The lamp body can rotate 360° and lock the angle. In this embodiment, the adjusting arm 530 is preferably a small electric mechanical arm. In other embodiments, a ball joint bracket with a common structure can be selected. The light source is a multi-spectral LED array, including red light (660nm), blue light (450nm), and far-red light (730nm) channels, with an adjustable light intensity range of 0-1000μmol / m²·s. The side supplementary lighting plate 520 is embedded in the side wall of the box and adopts a light guide plate diffusion design, with a supplementary lighting uniformity of >90%. The distance between the plant and the light source is adjusted by the lifting platform 230, and the light intensity changes inversely with the square of the distance (e.g., if the distance is shortened by 50%, the light intensity increases to 4 times).

[0058] The bottom of the placement tank 600 is connected to the water supply mechanism 800, which includes a peristaltic pump, a water level sensor, a connecting pipe, and a solenoid valve. The peristaltic pump is located on the outside of the tank 100, with a flow rate accuracy of ±0.1 mL / min, and supports gradient water supply (such as decreasing the water volume by 5% daily). The water level sensor is located inside the placement tank 600 and feeds back data to the control module in real time. The control module is electrically connected to the peristaltic pump and the solenoid valve. The control module has a built-in control program to control the peristaltic pump and the solenoid valve to start and automatically compensate for evaporation loss. The connecting pipe is located at the outlet end of the peristaltic pump and extends to the outer wall of the tank 100, with one end extending into the tank 100. A water injection hole is correspondingly opened on the placement tank 600, and a sealing O-ring is provided on the side of the placement tank 600 near the connecting pipe. The sealing O-ring abuts against the inner wall of the tank. The connecting pipe can communicate with the water injection hole for water supply. The connecting pipe is located in the sliding direction of the placement tank 600 and is located on the side wall away from the opening of the tank 100.

[0059] The stage 210 and the lifting stage 230 have heat insulation cavities inside, filled with aerogel heat insulation material (thermal conductivity 0.02W / m·K) to block heat conduction between adjacent surfaces.

[0060] The operating principle of this embodiment is as follows: The lifting assembly 420 drives the lifting frame 410 and the support platform 430 to move until they are flush with the stainless steel guide rail 310. The loading platform 210 and the lifting platform 230 are placed sequentially between the two placement slots 600. The locking block 290 engages and locks with the locking slot 211, and is fixed by electromagnet adsorption, completing the splicing of the loading platform 210, the placement slot 600 and the lifting platform 230. The loading platform 210 is pushed into the mounting slot 110 of the housing 100 along the slide rail mechanism 300, and the limit stop triggers a "click" sound to indicate that it has reached the correct position. The placement slot 600 is filled with a layered salt gradient matrix (bottom layer 1.0%, middle layer 0.5%, top layer 0.1%). NaCl); a partition plate 270 can be pushed into one side as needed, so that the first culture chamber 221 or the substrate layer can be in contact, and different salinity and no salinity can be selected for comparative cultivation. Alternatively, the substrate layers on both sides can be connected simultaneously as needed, and the height of the lifting platform 230 can be adjusted periodically or fixedly as needed, so that the seedlings are in different salinity environments or light environments for growth. Or, as needed, seedlings can be cultivated under the same initial conditions, and then after the seedlings grow and germinate, different salinity or gradient changes in salinity can be selected for comparison.

[0061] In other cases, seedlings can be raised together under the same initial conditions as needed. After the seedlings have grown and sprouted, they can be placed in the upper and lower spaces respectively to compare their cultivation in different external environments.

[0062] The illumination lamp 510 is turned on to simulate lighting, and the side supplement light panel 520 supplements blue light (accounting for 30%); the control module adjusts the day and night temperature difference according to the program (25℃ during the day / 18℃ at night).

[0063] Alternatively, a drought environment can be simulated by adjusting the flow rate of the peristaltic pump; water can be automatically replenished when the water level sensor triggers an alarm to prevent the plants from dehydrating and dying.

[0064] The lifting platform 230 shortens the distance between the plant and the light source by 50%, increasing the light intensity to 800 μmol / m²·s; the side supplementary lighting plate 520 enhances the proportion of red light (accounting for 60%), inducing photomorphogenesis response.

[0065] Record data according to different environmental conditions, and measure growth indicators such as plant height, leaf area, and root-to-shoot ratio; sample and analyze Na. + / K + Ion accumulation was assessed to evaluate differences in salt tolerance; temperature, humidity, light intensity, and water supply curves recorded by the control module were exported; and stress response kinetic models of different treatment groups were compared.

[0066] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
